When Webster's Added Jazz to the Dictionary

From The Atlantic:

In a musty Brooklyn bookstore this past weekend, I went looking for an old dictionary for a very special secret project. Among the teetering stacks of books, I came across a gorgeous 1927 Webster's International New Dictionary, and paging through it at Karloff down the street, I found myself drawn to the NEW WORDS section. These words were not invented in 1927, but represent additions to the book since its original publication in 1909. So, what we're capturing here is change between 1909 and 1927, a fascinating historical moment of great technological and social change.
